I'll confess to having perpetrated a fair number - at a time when I didn't know better. A few things, though: The immediate curtilage of a house is presumed to be private; at least in the US, one does not drive or walk directly up to someone's house without having business there. (Someone making a delivery, obviously, has business there.) I ordinarily will NOT hike on a service way or track across privately-owned land unless I see some indication that it is open, or I know what the situation is in advance. Of course, there are exceptions: for instance, I know of some woods roads that are public rights-of-way, dating to a time before the automobile, where landowners have attempted to close them. The local hiking club advises to hike them, openly and notoriously, disregarding the posters. (In at least one case that I'm aware of, the landowner eventually changed the posters to read, "PUBLIC RIGHT-OF-WAY ON PRIVATE LAND. STAY ON TRAIL") https://www.openstreetmap.org/way/291410854 is a public highway, whatever the posters say! But most of the roads that have signs like 'Johnson Lane // PRIVATE' are just farm driveways that I ordinarily wouldn't hike. I surely don't mark as `acccess=private` the service roads going to inholdings on public land, whoever maintains them. The last one I can recall mapping was https://www.openstreetmap.org/way/20631036 - and I marked it as `motor_vechicle=private` (it's signed 'no motor vehicles'), `foot=designated bicycle=no wheelchair=no atv=no ski=yes snowmobile=yes` and I left out `horse` because I have Absolutely No Idea, except for the fact that the trail was free of horse by-products. (Whether to use 'track', 'service' or 'residential' for that way is controversial and in the end is also meaningless. It's there mostly for forestry. Someone happens to have a cabin on it. In the field, it's a pair of ruts winding off into the woods.) I haven't had any trouble getting OSMand to navigate to a house on a road marked `access=private`. It pops up a warning that my destination is on a private road, and asks whether it's OK to route over it - and then does so happily. (Much more happily than before I tweaked https://www.openstreetmap.org/way/165370475 to restore network connectivity. When I was driving on it, it wound up scolding me, "You have been driving off road for the last 1.5 miles. Please proceed to the highlighted route!") It's not just whatever custom system Amazon uses. I'm perfectly willing to believe that overzealous application of 'private' breaks _some_ routing engines, but 'breaks routing for everyone' is a bit hyperbolic. -- 73 de ke9tv/2, Kevin _______________________________________________ Talk-us mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk-us
